Thanks Todd
I also have SET CONFIRM OFF (default VFP setting), so I'll try your solution.

>>>Checkboxes occasionally show this behavior. From a previous thread:

>>>*  Event: chkBaseRefreshOK.Valid()
>>>*  When SET CONFIRM is ON, the native checkbox control doesn't change its
>>>*  visible state in response to a mouse click or space bar press until the
>>>*  user exits the control, for example with the TAB key. This code fixes
>>>*  that behavior.

>>>with this
>>>   .value = EVALUATE(.ControlSource)
>>>   NODEFAULT
>>>endwith
